KNOWLEDGE OF GLASS-LINED STEEL EQUIPMENT
"Glass-Lined Steel" is a material of construction that combines the strength of steel with the corrosion resistance of glass. It is made by fusing a thin layer of glass to steel at high temperature, creating a strong, chemically bonded base coat, upon which subsequent layers of corrosion-resistant glass are fused.
Application of glass-lining begins with careful metal surface preparation. We have automatic grinding machines to ensure the metal surface is perfectly smooth, which is very important for glass-lining process. The surface of glass-coated in successive layers: The base coat is covered by four or five additional layers of corrosion-resistant glass. Each layer is sprayed on, dried, fused in electric furnaces and cooled at controlled temperature to reduce warpage and to obtain desired physical and chemical properties.
For final acceptance, under Chinese national standard and quality standard of J.H. Equipment, the glass-lining must be tested within a required thickness range and pass a 20,000-volt DC spark test, assuring highest integrity. Before shipment, J.H. Equipment will make a repeat spark test with 5,000 or 7,000 volts as per requirement of customers.
The major advantages of glass-lined steel are:
* Wide application due to broad range of corrosion resistance. Glass-lining of J.H.Equipment has perfect property of corrosion-resistant against various organic and inorganic acids, weak alkaline except hydrofluoric acid and hot phosphoric acid with high concentration.
* Essentially inert-selected where super-high purity is required, will not affect product flavour or colour.
* Excellent anti-stick property, no product adherence, easy clean ability and product changeover.
* High working temperature available, over 200-degree C, better than loose plastic-lined vessels.
* Much more economical than super alloys
KNOWLEDGE OF BOROSILICATE GLASS EQUIPMENT
Borosilicate glass is a type of glass with the main glass-forming constituent’s silica and boron oxide. Borosilicate glasses are known for having very low coefficients of thermal expansion, making them resistant to thermal shock, more so than any other common glass. Now borosilicate glass G3.3 is the main material for production of glass equipment, pipes and fittings. G3.3 is short name for borosilicate glass with coefficient of thermal expansion of (3.3+-0.1) x10-6/k-1. It's also called Pyrex.
The major advantages of borosilicate glass for industrial use
*Perfect corrosion resistant property against various acids.
*Wide operation temperature range
*It's hydrophobic characteristics makes it easy to clean the complete chemical or pharmaceutical reaction unit
*Another obvious advantage is its transparency, operators can see clearly the whole reaction process
All glass equipment, pipes and fittings produced by J.H.Equipment is made of G3.3 borosilicate glass according to international standard ISO3587.
